Mr. Gasket2471B Domestic Thermocap 16 Psi-Blue

Great fit, great looking, very accurate, great value, ALL OF THE ABOVE!!!!!!!

Love the look and color BUT it doesn’t want to fit a standard radiator fill.Going to try it on another vehicle now to see what happens. Hopefully it will work!

Works great

They really look good. Nice dress up item.I only use mine for diagnostic purposes but if I had a show car it would look great.The first one I got the temp was way off so they sent me another one quickly. Very impressed as had along time to return the first one NC.The second one was dead on accurate but I found it leaked around the top seal (by lifting up the overflow) so had to bend the hold downs slightly so it would seal and siphon the water back into the radiator when it cooled down.Now it works and looks perfectly. A real bargain too. A great check for the inaccurate gages in some cars today!!Due to the attractive smooth shape it can be a little hard to remove by hand - especially when hot. I used a open wrench with a rag to protect the pretty chrome.

Good product at a fair price

Twenty words are not necessary to comment on this item so I will have to fill in. Hmmmm! It's on my '66 GTO. It fits! It works! It's pretty accurate (I checked it with a professional scientific lab thermometer. It takes considerable effort to install or remove it when compared to a standard radiator cap. Quality looks good

I bought this because my old cap wasn't holding pressure anymore and the idea of a second temperature sensor appealed to me. It did the trick to stop the leak and it does let me know the coolant temperature. The downsides are the cheap looking finish and the fact that I needed to bend a tab on it to make it fit my radiator. If you can get it for a good price I'd say go for it, but don't go out of your way or overbudget for it.

The radiator cap comes with a rated PSI of 16Lbs, which was good for my applications. The cap performed as advertised providing accurate temperatures and reliable performance. I use it as a tool to check the accuracy of all my heat gauges as I have several show cars. I live in a high temp area where the temps often exceed 105 deg. in the summer, thus having the provided accurate Radiator cap temp. is important.
